XYZ interview questions

There were four round 2 were written rounds one was technical and one was HR round. In first written round there were MCQ based on the basic concepts of C++ ,OOPS, CN, OS and DBMS and in second written round there were medium to hard level DSA problems.

It was good, but mostly asked about os, ca so, I wasn't able to clear the round. It was good, but mostly asked about os, ca so, I wasn't able to clear the round.
